depending on your tolerance to a tough ride!
the higher the pressure the better the handling!
max pres for the tires is 50 psi. I am running 45 psi
in the front and 40-43 psi in the rear. Try 45 all around
and if that is too rough lower the pres 2 psi each time
until it is tolerable.
let me know if you have any more q's
